6.
Turn the adjusting bolt clockwise
to gradually
increase the pressure until the gauge indicates the
desired outlet pressure (under no flow condition).
7.
Reopen a downstream valve. During flow, there will nor-
mally be a pressure falloff of 3 to 15 psi depending on
the amount of water flow.
8.
Tighten the locknut by turning clockwise
until tight.
Do not overtighten.

Replacing the Cartridge (See Fig. 3)
The working parts of the D05T, including diaphragm, valve
seat, and disk are all contained in a replaceable cartridge. To
replace the cartridge:
1.
Shut off the supply valve and open a downstream faucet
to relieve the system pressure.
CAUTION
To prevent injury and/or equipment damage,
loosen locknut and turn adjusting screw
counterclockwise
to remove spring tension.
2.
Loosen locknut and turn adjusting screw counterclock-
wise
to remove spring tension.
3.
Remove the bonnet and washer using an adjustable
wrench, socket, or box-end wrench.
4.
Remove the cartridge using two screwdrivers as levers.
5.
Attach new O-rings and screen onto the new cartridge.
Make sure O-rings are properly installed above and
below the screen.
6.
Insert the new cartridge. Do not scratch the sides.
7.
Place the washer on top of the cartridge.
NOTE: The inner lip must be pointing up to avoid dam-
aging the diaphragm.
8.
Replace the spring, spring cup, and bonnet.
9.
Readjust the outlet pressure to the desired setting by
using the procedure described in Changing the Outlet
Pressure section.
